Query Acceleration
๐๏ธ Resource group
This topic describes the resource group feature of StarRocks.
๐๏ธ Query queues
This topic describes how to manage query queues in StarRocks.
๐๏ธ Query Management
Number of user connections
๐๏ธ Memory Management
This section briefly introduces memory classification and StarRocksโ methods of managing memory.
๐๏ธ Spill to disk
This topic describes how to spill intermediate computation results of large operators to local disks and object storage.
๐๏ธ Load Balancing
When deploying multiple FE nodes, users can deploy a load balancing layer on top of the FEs to achieve high availability.
๐๏ธ Manage replica
This topic describes how to manage data replicas in your StarRocks cluster.
๐๏ธ Blacklist Management
In some cases, administrators need to disable certain patterns of SQL to avoid SQL from triggering cluster crashes or unexpected high concurrent queries.
๐๏ธ Add labels on BEs
Since v3.2.8, StarRocks supports adding labels on BEs. When creating a table or an asynchronous materialized view, you can specify the label of a certain group of BE nodes. This ensures that data replicas are distributed only on the BE nodes associated with that label. Data replicas will be evenly distributed among nodes with the same label, enhancing data high availability and resource isolation.
๐๏ธ File manager
With file manager, you can create, view, and delete files, such as the files that are used to access external data sources: public key files, private key files, and certificate files. You can reference or access the created files by using commands.
